2 April 28, 1997FOREWORDThis Pamphlet is reissued under the authority of DoD Directive , “Information Security Program,” December 13, It prescribes guidance through examples, on the markings for classified national security information. It supersedes the 1982, PH guide.The guidance contained is derived from the E.O , “Classified National Security Information,” its implementing instructions, and the marking guide developed by the Information Security Oversight Office. This pamphlet applies to the Office of the Secretary of Defense (OSD), the Military Departments, the Chairman of the joint Chiefs of Staff, the Defense Agencies, and the DoD Field Activities (hereafter referred to collectively as “the DoD Components”).Marking classified information serves several purposes in the Department of Defense. It alerts holders to the presence of classified information, identifying the exact information or portion that needs protection; provides guidance for downgrading and declassification; gives the reason for the initial classification decision; and warns the holders of any special access, controls, or safeguarding requirements. While we can not anticipate every marking situation, this pamphlet provides the basic ground rules that apply to all classified information, regardless of the media used. For specific situational needs, contact your agency’s security officer for guidance.This Pamphlet is effective immediately for use by all the DoD Components. The Heads of the DoD Components may issue supplementary instructions when necessary to provide for unique requirements within their organizations.Send recommended changes to the Pamphlet to:Office of the Assistant Secretary of Defense for Command, Control,Communications, and IntelligenceDirector, Security Programs6000 Defense PentagonWashington, DCThe DoD Components may obtain copies of this Pamphlet through their own Publications channels. Approved for public release; distribution unlimited. Authorized registered users may obtain copies of this Publication from the Defense Technical Information Center./S/Emmett Paige, Jr.21

4 Security RemindersA. Classification decisions are either original or derived.B. Only individuals occupying positions specifically authorized in writing may classify documents originally.C. Only individuals with the appropriate security clearance, who are required by their work to generate classified source information, may classify derivatively.D. There are three levels of classification, “TOP SECRET”, “SECRET” and “CONFIDENTIAL.” Do not use other terms, such as “Official Use Only,” or “Administratively Confidential,” to identify classified national security information.E. Information shall not be classified for any reason unrelated to the protection of national security.F. Classifiers are responsible for assuring that information is appropriately classified and properly marked. The proper markings include declassification instructions.G. To have access to classified information, a person must have a security clearance at an appropriate level, a signed SF 312, “Classified Information Nondisclosure Agreement,” and the “need-to-know.”H. Individuals who believe that information in their possession is inappropriately classified, or inappropriately unclassified, are expected to bring their concerns to the attention of their security manager or the classifier of theinformation for resolution.I. Classified information shall not be discussed or read in public places. It should not be left unattended, even for a short time in automobiles, hotel rooms, private residences or public lockers. Only approved security containers are authorized for storage.J. Classified information shall not be discussed on non-secure telephones. “Talking around” is a dangerous practice and does not provide adequate protection to classified national security information.K. Notes, rough drafts, informal working papers, and other preliminary documents must be handled and destroyed as classified information. This is especially important with computer generated documents that often go through several revisions. Apply the markings as the document is being created.43

5 SECTION 1 - Marking “Originally Classified” DocumentsSECRETOFFICE OF THE SECRETARY OF DEFENSEWASHINGTON, DCMEMORANDUM FOR DASD (I&S)SUBJECT: Classification Markings (U)1. (U) This is an example of a document that contains originally classified information. Standard markings are required for all documents as shown here. These markings include:a. (U) Portion marking(s) for each section of a document to reflect the classification of the information. When using subsections such as shown here, individual markings are used. When subsections are not marked, the information is protected at the level of protection shown by the overall section.b. (U) Overall markings conspicuously using larger font size or bold.c. (U) A “Classified by” line that includes the name or personal identifier and position of the originator.d. (S) A reason for classification as shown on page 8 of this guide.e. (U) A “Declassify on” line that indicates the following:(1) The date or event for declassification not to exceed 10 years.(2) The date that is 10 years from the date of the original decision.(3) An extension beyond the initial 10 years of classification.(4) An authorized and applicable exemption category(ies) as described on page 10 of this guide.2. (S) If this paragraph contained “Secret” information, the portion would be marked with the designation “S” in parentheses. If the paragraph contained “Confidential” information, the portion would be marked with the designation “C” in parentheses.Classified by: Emmett Paige, Jr.ASD(C3I)Reason: (a) and (d)Declassify on: December 31, XXXX1.b.date1.a.1.a.1.c.1.d.1.e.Note: A line followed by a reference number, throughout this pamphlet, cites the paragraph number foundon the same page.54

6 OFFICE OF THE SECRETARY OF DEFENSEPortion Markings and Overall Classification Marking3.SECRETOFFICE OF THE SECRETARY OF DEFENSEWASHINGTON, DCdateMEMORANDUM FOR DASD (I&S)SUBJECT: Portion Markings and Overall Classification Marking (U)1. (U) The first step in marking a document is to identify the classification level of each portion contained in the document. This includes each paragraph, subjects, and titles. Only by identifying the proper classification for each portion can the overall classification level be determined.a. (U) The three sample paragraphs shown here contain “Unclassified,” “Secret,” and “Confidential” information, respectively. Portion markings consist of the letters “(U)” for unclassified, “(C)” for “Confidential,” “(S)” for “Secret,” and “(TS)” for “Top Secret.”b. (U) These abbreviations are placed, in parentheses, before the portion, or fter the title to which they apply.c. (U) Whenever possible, use an unclassified title or subject line. If a classified title and/or subject is necessary, follow it with a short, unclassified title.2. (S) The second step in classifying a document is determining the overall classification of the document. The overall classification is determined by the highest classification level of information contained in the document. In the example shown here, “Secret” is the highest level of classification. This is paragraph 2. If it were to contain “Secret” information, this portion would be marked with the designation “S” in parentheses.3. (C) “Conspicuously” place the overall classification at the top and the bottom of the page. This is paragraph 3. If it were to contain “Confidential” information, this portion would be marked with the designation “C” in parentheses.1.1.1.&2.Classified by: Emmett Paige, Jr., ASD(C3I)Reason: 1.5 (a) and (d)Declassify on: December 31, XXXXSECRET65

(U) Mark each internal page with the overall classification, or with the highest classification level of information contained on that page.5. (S) This is paragraph 5. If it were to contain “Secret” information, this portion would be marked with the designation “S” in parentheses.4. (U) When using overall marking on every page of a document, ensure that extracts of the document are remarked to reflect actual classification and source description.5. (U) This is paragraph 5. If it were to contain “Unclassified” information, this portion would be marked with the designation “U” in parentheses.SECRETUNCLASSIFIEDSECRETSECRET4. (U) This is paragraph 4. It is an unclassified paragraph and is therefore marked with a “U” as other portions on this page are classified. Should this paragraph be used to create another document, the information taken from this paragraph from this page would remain unclassified.5. (S) This is paragraph 5. Should this paragraph contain “Secret” information, this portion would be marked with the designation “S” as indicated at the beginning of this paragraph. The overall classification on this page is marked “Secret” because this paragraph contain Secret information, which is the highest(S) level of classification contained on the page. When a classified or unclassified paragraph is too long and must be carried over to another page, the classification MUST be carried forward as well.6. (U) This is paragraph 6. If it were to contain only “Unclassified” information, this portion would be marked with the designation “U” in parentheses.SECRET9SECRET1076

9 OFFICE OF THE SECRETARY OF DEFENSE“Classified by” and “Reason for Classification” LineSECRETOFFICE OF THE SECRETARY OF DEFENSEWASHINGTON, DCMEMORANDUM FOR DASD (I&S) August 1996SUBJECT: “Classified by” Line (U)1. (S) The third step in properly marking a document is to annotate the original classification authority on the document. This is accomplished by placing the original classification authority on the “Classified by” line. The “Classified by” line should include the name or personal identifier of the actual classifier and their position. If the identification of the originating agency is not apparent on the face of the document, place it below the “Classified by” line.2. (U) Each original classification decision shall state a reason for classifying. Classification may be applied only to information described in the following categories as specified in section 1.5 of Executive Order 12958, “Classified National Security Information” are:a. (U) Military plans, weapons systems or operations.b. (U) Foreign government information.c. (U) Intelligence activities (including special activities), intelligence sources or methods, or cryptology.d. (U) Foreign relations or foreign activities of the U.S., including confidential sources.e. (U) Scientific, technological, or economic matters relating to the national security.f. (U) U.S. Government programs for safeguarding nuclear materials or facilities.g. (U) Vulnerabilities or capabilities of systems, installations, projects or plans relating to the national security.3. (U) The original classifier shall identify a concise reason for classification which, at a minimum cites the applicable classification categories in section 1.5 of E.O as the basis for classification. Original classifiers must ensure that the exemption category selected is consistent with the reason for classification cited on the document.1.Classified by: Emmett Paige, Jr., ASD(C3I)Reason: Military Plans; Foreign RelationsORReason: 1.5 (a) and (d)Declassify on: December 31, XXXX2.&3.3.SECRET98

When determining the duration of classification, choose one of the following three declassification instructions: (Whenever possible, select the declassification instruction that will result in the shortest duration of classification.)1. Date or EventWhen possible, identify the date or event for declassification which corresponds to the lapse of the information’s national security sensitivity. The date or event shall not exceed 10 years from the date of the original classificationOR2. Ten Year DurationWhen a specific date or event cannot be determined, identify the date that is 10 years from the date of the original classification3. Exemptions from the Ten Year RuleIf the information has been determined exempt from declassification at 10 years by the original classifier, place the letter “X” plus a brief recitation of the exemption category(ies) OR the letter “X” plus the corresponding number to that exemption category(ies) in section 1.6(d) of Executive OrderSee next page for a list of these exemption categoriesClassified by: Emmett Paige, Jr.ASD(C3I)Reason: 1.5(a) and (d)Declassify on: December 31, 2002Declassify on: Completion of OperationorSeptember 1, 1995(Date of original classification)Classified by: Emmett Paige, Jr.ASD(C3I)Reason: 1.5(a) and (d)Declassify on: September 1, 2005Classified by: Emmett Paige, Jr.ASD(C3I)Reason: 1.5(a) and (d)Declassify on: X-Damage RelationsorDeclassify on: X6109

12 Information Transmitted ElectronicallyWorking PapersWorking papers are documents and material accumulated or created in the preparation of finished documents and material. Working papers containing classified information shall be:1. Dated when created.2. Marked with the highest classification of any information contained therein.3. Protected in accordance with the assigned classification.4. Accounted for, controlled, and marked in the manner prescribed for a finished document of the same classification when retained more than 180 days from date of origin or released by the originator outside the activity. This requirement extends to all classification levels.Information Transmitted ElectronicallyInformation transmitted electronically, and retained as permanent records, must be marked, as would any other classified document, with the following special provisions:1. The first item in the text must be the overall classification of the information.2. For information printed by an automated system, overall and page markings may be applied by the system, provided they stand out conspicuously from the text. In older systems, this may be achieved by surrounding the markings with asterisks or other symbols.3. Properly completed “Classified by” anf “Reason” lines or “Derived from” line, declassification instructions, and downgrading instructions (when appropriate) must be included in the last line. Declassification and downgrading instructions shall not be used for information containing Restricted Data or Formerly Restricted Data.4. The following abbreviations may be used:“CLASS” for “Classified by”“RSN” for Reason (only necessary for originally classified information)“DECL” for “Declassify on”“DERV” for “Derived from”“DNG” for “Downgrade to”See example of an electronically transmitted message on the next page.1211

14 SECTION 2 - Marking “Derivatively Classified” DocumentsSECRETABC Battalion Report (U)Derivatively Classifying From a Source Document and Portion Markings (U)1. (S) Derivative classification is the act of incorporating, paraphrasing, restating, or generating in new form, information that is already classified, and marking the newly developed material consistent with the markings of the source information. The source information ordinarily consists of a classified document or documents, or a classification guide issued by an original classification authority. This paragraph contains incorporated information taken from the second paragraph of a source document, a paragraph marked “Secret.” Therefore, this paragraph is marked with an “S.” This, “derivative” document contains no other classified information. Therefore, portion mark all other portions with a “U.”2. (U) When using a classified source document as the basis for derivative classification, the markings on the source document determine the markings to be applied to the derivative document.(a) (U) As with documents created by original classifiers, each derivative document must have portion markings and overall classification markings.(b) (U) The “Classified by” line is replaced with a “Derived from” line. The “Reason” line, as reflected in the source document(s) or classification guide, is not required to be transferred to the derivative document. Examples are on pages 14 and 15 of this guide.SECRET1 September, 1996Special Report--ANX-128 (U)1. (U) This is paragraph 1 which contains “Unclassified” information.

27 Special Access Programs1. “Special Access Programs” (SAPs) are established IAW Chapter 8, DoD R, “Information Security Program Regulation.” SAPs are created only when absolutely necessary to protect the Nation’s most sensitive and critical information or when required by statues. Establishment shall be consistent with law, policy, and regulations, and be based on a determination that the threat and/or vulnerability (e.g. sensitivity or value of the information) warrants enhanced protection.2. Any DoD program or activity employing enhanced security measures exceeding those normally required for information at the same classification level shall be established, approved, and managed as a DoD SAP. Examples of such enhanced security measures include the following:a. use of any special terminology, including code words, other than an unclassified nickname, to identify or control information dissemination;b. personnel security investigative or adjudicative requirements more stringent than those required for a comparable level of classified information;c. specialized non-disclosure agreements;d. exclusion of a classified contract (use of carve-out); ore. a central billet system to control the number of personnel authorized access.3. All DoD programs which operate under the above enhanced procedures are considered to be SAPs, including (i) Programs managed under special delegation authorities previously approved by the Secretary of Defense or Deputy Secretary of Defense; (ii) Programs sponsored by other departments or agencies, but for which DoD participants manage internal DoD security controls (e.g. DoD-managed subcompartments of larger, non-DoD SAPs; (iii) and Programs conducted in support of, or in cooperation with, other departments, agencies, branches of government, or other governments. SAPs may only be approved by the Secretary of Defense or Deputy Secretary of Defense.4. All marking provisions previously described in this guide apply to SAPs. Additional markings include: (i) the use of special distribution notices such as “Special Access Required” (SAR); and/or (ii) an assigned program nickname(s) or code word(s)5. To differentiate a nickname from a code word, remember that:a. A nickname is a combination of two unassociated and unclassified words.b. Nicknames are normally typed in ALL CAPS.c. A code word is a single word assigned a classified meaning by appropriate authority.d. The code word is classified Confidential or higher.e. All nicknames and code words are issued through the DoD Components (usually SAP channels) and strictly controlled.6. The unclassified examples on the following two pages, depict common markings for SAP documents. The examples are for ILLUSTRATIVE USE ONLY. The format for markings should be adjusted to accommodate software applications and production efficiency. For instance, the examples show the overall classification and nickname/code word in the header and the overall classification and special access requirement in the footer.2726

28 TOP SECRET/TWISTED FEATHER (U) TOP SECRET/SPECIAL ACCESS REQUIREDSAP “NICKNAMES”SAPs use nicknames for control of dissemination and “need-to-know.” Nicknames are assigned to the program when the SAP is approved. Nicknames are designated by two unassociated words, which are unclassified by themselves (i.e. TWISTED FEATHER).TOP SECRET/TWISTED FEATHER (U)OFFICE OF THE UNDER SECRETARY OF DEFENSE FOR POLICYJune 25, 1996MEMORANDUM FOR SPECIAL ACCESS PROGRAM CENTRAL OFFICESSUBJECT: Identification and Marking of Classified Documents (U)1.

Refer to the SAP Security Procedure Guide for instructions.2827

29 TOP SECRET/CODE WORD (S) TOP SECRET/SPECIAL ACCESS REQUIREDSAP DocumentsSAP “CODE WORD”In addition to nicknames, SAPs also use code words for control of dissemination and a “need-to-know”. Code words, like nicknames, are assigned to the program when the SAP is approved.

30 Section 4 - “Other” Automatic Declassification - The 25-year rule 291. The automatic declassification provision (Section 3.4) of E.O , requires declassification of information in permanently valuable historical records (as defined by Title 44, U.S. Code) 25 years from the date of original classification, whether or not the records have been reviewed. Subsequently, all classified information in such records shall be automatically declassified no later than 25 years from the date of its original classification, with the certain exceptions outlined in the E.O.2. Only the Secretary of Defense and the Secretaries of the Military Departments may exempt information from this automatic declassification, and only under certain circumstances. Information exempted from automatic declassification at 25 years remains subject to the mandatory and systematic declassification review provisions.3. If the record is exempt from 25 year declassification, the following markings are used:a. Site the exemption categories for number or phrase on the “Declass” lineExample: 25X ____25X, Human Sourcesb. List a date for “Declass” reviewReview 4/15/104. Classified information, contained in records that are more than 25 years old, and which have been determined not to have permanent historical value, and are scheduled for disposition in agreement with the National Archives and Records Administration (NARA), is not subject to automatic declassification. Agency retention and destruction requirements apply.5. Consult your security officer or records manager for additional information.3029

31 Marking Information “Other Than” DocumentsCharts, maps, equipment, drawings and photographsInformation must be marked with the highest level of classification regardless of what form that information may take. The next few pages show examples of marking situations to guide you. The principles are the same. Portion marking, overall marking, classification byline and declassification instruction. The legend, title and scale blocks in the following examples are treated as portions of the document. Ensure that the overall classification of the product shows when the item is folded or rolled.SECRETSECRET(U) Maps may have the portion marking inside or outside the map area.
